LESTER O. NAYLOR, OF NEW YORK, N. Y., ASSIGNOR O1? ONE-HALF TO OTTO HAUERBACH, OF NEW YORK, N. Y.

i HEATER FOR AUTOMOBILES.

Be it known that I, Lnsrna O. NAYLOR, a citizen of the United States, and residing at- New York, in the county and State of New York, have invented certain new and useful Improvements in Heaters for Automobiles; and I do hereby declare the following to be a full, clear, and exact description of the same, reference being had to the accompanying drawings, forming part of this specifi- .eation, and to the figuresand letters of reference marked thereon. i

This inventionrelates to apparatus for supplying heat tot-he passenger space or spaces of an automobile vehicle from a portion or all of the hot exhaustgases fromthe motor. Various heating arrangements adapted for the circulation of the exhaust gases have been proposed,'but such prior appa-ratus has usually required more or less extensive alteration in the mechanism, framework, flooring or bodies of the vehicles.

The object of the present invention is to provide an exceedingly simple form of apparatus which may be readily installed in practically any type of pleasure or commercial vehicle without the necessity of any alteration or change in any portion of the vehicle itself further than the perforation of the "flooring for thepassage of the pipes through which the heated-gases pass to and from the heater.

leferring to the accompanying drawnigge -Figure l is an elevation looking at the rear of. an automobile with the tonueau seats removed and portions broken away to show the heater and its connections; Fig. 9 is a vieveshowin in end elevation the heater which is located in the front portion of the tonneau just above the floor line, this view also showing a portion of the main exhaust pipe from the motor and the heater ferred form-of heater showing in dotted lines the reverse bend at the end remote from the exhaust pipe connection and with portions broken away; Fig., 4r. is a section on the line lt'l, Fig. 3; Figs. 5 and 6 are detail views of the valve controlling and passage of exhaust gas-es to the heater and the operating lever therefor.

the pipes.

seen that the conventional parts of the vehicle arerepresented, the view showing the back portions of the-front seats. The usual exhaust pipe A extends back beneath the floor of the body and is preferably provided with t-he usual muffler B of known constructionj At a point preferably forward of the muffler, the exhaust pipe or duct A is provided with a lateralbranch C, and at the'junction of thebranch and main duct A a valve'is located and adapted to be oper- 'ated bya lever or arnrD, as will be presently described soas to control the flow of gases through the branch duct. The branch duct C extends upwardly through the floor of the vehicle, but preferably. has incorporated'in'it a uniou (2', and at the upper end it joins the heater pipes which extend transversely above the'floor of the vehicle and are preferably in two" lengths l l and E, arranged parallel and one-above the other.

'Said pipes are connected at their farther endsby a reverse bend e, and the lower sec tion E at its end nearest the branch C is carried down by means of anelbow coupling c and'eonnected with a pipedi seharge Patented Aw. 5,1913.

(' which preferably leads into the open air,

as shown, but may be carried away to any suitable point and connected with the main exhaust pipe.

In the preferred arrangement the heater pipes. are supported above thiv floor and out of any direct contact with fine body of the vehicle, while contact of r'toes, garments or the feet of the passenger; with the heater pipes is prevented and a finished appear- .ance given the structure by u. shield which preferably takes. the form of an oval in cross section with one side or theoval for the free circulation of air about the pipes. As shown, the shield F is made of sheet metal of ornamental form and itis spaced from the heater pipes, being mounted in end brackets G and connected with the pipes'by clips F held screws F passing between The heater occupies the most convenient position for a foot rest and to afford a'firin rest against which the passengers may brace themselves, a. foot rest or bar H is arranged in position immediately in rear of the heater, as shown clearly in Figs. .1 and l, the preferred location of the barbeing such that the feet of the passengers will be held in an 1 inclined position upwardlyover the heater main exhaust'pipe beyond the branch.

so as to obtain the full benefit the heat radiated from the heating pipes and shield.

The bar it not only forms the footrest, but

constitutes a part of the heater itself; thus it is preferably provided with a longitudinal. channel 71 for the reception of the edge otthe shield, and at itsen'ds' it is connected with the end bracket G in which the ends of the shield are confined. The connection between the bar' and brackets may conveni-cntly be formed by screws 71. passing through the brackets and into the ends of the bar as will be readily understood. The lower-edge of the shield is also preferably strengthened by an edge bar L havi-ng a channel for the shieldedgc and connected with the end brackets by screws or other fastcning means. a When desired the shield may also be connected with the end brackets as by angle piecesM and screws as shown.

The flow of exhaust gases from the exh aust pipe through the heater is controlled by. a valve D located at the junction of the heater branch with theimain exhaust pipe, said. valve being so constructedthat as the heater branch is opened the main exhaust pipe correspondinglyrestricted at a point just beyond the branch, thereby diverting 'a"'portion of the gases through the heater and at the same time avoiding any material "increase in the resistance to the flow of the gases which might cause backpressure and cut down. the power of the engine.

The construction of the valve will be readily understood from Figs. 5 and 6, wherein it will be seen that the body or housing D of the valve has a transverse cylindrical chamber (Z into which tlie'main and branch exhaust'dncts open at an angle to each other, and within the chamber is a segmental valve gate-D. The cylindrical face of the gate is of such size as to completely close the branch duct opening when turned to proper position, and when the gate is swung to open or ;)artly'open the branch it correspondingly closes or partly closes the The valve gate is journaled in bearings in the ends o -heads of the body, one of which may be removable, and a lever arm D secured to the valve gate serves as the means whereby the gate may be adjusted.

In the preferred arrangement the arm D is connected by suitable link or red connections a with an operating lever or arm 0 pivotally mounted on a sector O secured on the back of the front seat or other convenient part ofthe vehicle body where it the parts in the position to which they have been adjusted.

From the foregoing, it will be seen that the heating apparatus is of such character that it may be readily installed in practically any make or construction of automobile without requiring any alteration of either the mechanism, body or framing. It forms not. only an etlieientheater but constitntes a foot rest of approved character which is ornamental andin keeping with the style of the most approved types of ye hiele. ard size and the only fitting which isnecessary for each installation is the ordinary pipe connection between the heater and the exhaust pipe branch: This may require longer or shorter nipples or pipe sections,

as the case may be, for different types of vehicle, but sections of pipe of standard size are readily available and it. therefore becomes possible for an ordinary mechanic to;

install one, of the heaters in any vehicle without in any wise mutilating the body or frame for the accommodation of the apparatus.

Having thus described my invention, what I claim as new and desire to secure by Letters Patent of the United States, is: 1.. A heating apparatus for automobiles,

embodying parallel communicating heaterpipes arranged transversely of the vehicle above. the floor. of the same, a non-inflammable shield around and spaced from the The heaters may be made of standheater pipes and open on the rear side for the passage of heated air, brackets for sup portingsaid shield and heater pipes above the vehicle floor, a foot rest bar carried by the brackets, a duct for the exhaust gases from the engine communicating with the heater pipes, and means for controlling the passage of heated gases to the heater pipes.

2. A heating apparatus for automobiles,

embodying a duct for thepassage of exhaust gases, heater pipes in communication with said duct and arranged transversely of'the vehicle above the floor of the same, end
